Abstract

The present invention generally relates to the mounting of panes or windshields in a frame, particularly to the mounting of panes or windshields of a vehicle, e.g. an automobile, in the body frame work. The invention provides a pane or windshield ready to be mounted comprising, along its edges, a first profiled bead of adhesive material, already cured and being elastic but not plastically deformable. The first bead comprises an essentially closed hollow chamber and in its interior a second bead of plastically deformable not yet cured adhesive material consisting of a substance chemically compatible to the material of the first bead. The second bead, serving as the real adhesive material, is protected from environmental influences without the need to remove a cover foil or a packing prior to mounting the window.
